Systems of many particles evolving through the well-established theories of electromagnetism and quantum mechanics often collectively organize themselves in elegant ways. As a condensed matter theorist, Dr Barnett focuses on predicting and understanding such behaviour from a microscopic basis. He is particularly interested in systems where quantum mechanics and interactions play a crucial role.  His recent research has focused on elucidating collective effects in ultracold atomic gases.
